GNOME Bugzilla – Bug 651704
[Feature request] Disable sound during sound volume adjustment
Last modified: 2011-06-10 14:03:53 UTC
When you adjust the system sound volume, Gnome plays a sound; in Mac OS X happens the same thing, but you can mute this noise if you keep pressed the shift key. This is a very cool feature because if you are listening to music or watching a film, hearing other sounds could be very annoying.
commit 1d41ab388a06844c4b46cee6e396a4976f136770 Author: Bastien Nocera <hadess@hadess.net> Date: Fri Jun 10 15:00:33 2011 +0100 media-keys: Make sound changes quiet with Alt <Alt>+volume control keys will change the sound, without playing a notification sound, which can be useful when things need to be quiet. Note that this doesn't use the settings stored in GSettings, but is hard-coded for those audio keys. https://bugzilla.gnome.org/show_bug.cgi?id=651704
